Analyses of Heterosis in Major Agronomic Characters of Dwarf Castor
摘要
Abstract
Analyze the heterosis of major agronomic characters of four dwarf castor Lm markers female line and four restorer line and 16 F1 hybrid combination each other, which are bred in Tongliao Agricultural & Science Institute just now. The results indicates that the heterosis of F1 are different with their different characters. Among 18 agronomic characters, the grain weight and hundred-grain weight of single plant, these both characters are positive heterobehiosis. The maximum grain weight of single plant is 11.79%.This suggests that grain weight of single plant of dwarf castor are higher heterosis. So it's feasible to choose and cultivate the a hybrid strain which can be extremely high singe yield. During the growing period, plant's height showed negative heterobeltiosis,-19.02% and-14.37% respectively. This shows that it is effective to choose and cultivate the short-growing period and small- height plants dwarf castor, but the positive choosing about plant's height in Lm markers female line is unfavorable to the lowing of the hybrid strain plant height.关键词
